Google is an amazing resource - and often it bounces you to YouTube videos of folks demonstrating just about anything!
I just learned to use a circular saw, which was pretty darn intimidating at first! I also just bought a tile saw, and am scouting garage sales for a jigsaw. I also saw Home Depot offers classes on a bunch of stuff too.
It is very liberating to do it ourselves when push comes to shove, but I also don't hesitate to ask when I need help. I have a great neighbor couple who have been good with stepping in when needed. Sometimes, there are things just too big for one person - and a woman no less.
I would say you are being challenged by the universe, and I hope you are feeling much more confident in your ability to take care of yourself and your home. I am pretty darn proud of myself, and you should be too!
Stay strong!
